The IMD issued a heavy to very heavy rain warning for several Telangana districts, including Hyderabad, for September 24-25, as the same Bay of Bengal weather system that brought extreme rain to Odisha and Andhra Pradesh a day earlier moves further inland.

A single weather system producing warnings for different states on consecutive days is a useful reminder that a depression’s impact is not confined to its landfall point. As such systems move inland, they weaken gradually while still carrying enough moisture to produce significant rain well beyond the coast.

This also explains why forecasters issue rolling, updated warnings rather than a single static alert: a system’s exact track and intensity can shift meaningfully within 24 hours, changing which specific districts face the highest risk.

For residents in a state like Telangana, downstream of a coastal landfall, the practical implication is that a system reported as making landfall elsewhere is not necessarily over for them, and it is worth checking updated local warnings rather than assuming the risk has passed once a coastal landfall is reported.

The broader pattern, of Bay of Bengal depressions moving from coastal states into the interior during September and October, is a routine part of India’s post-monsoon weather and is one reason inland states also maintain seasonal flood-preparedness measures.

Local authorities in Telangana have been monitoring low-lying and flood-prone areas as the rain warning remains in place.

Residents in the affected districts have been advised to avoid waterlogged roads and stay updated on local weather alerts.

The system had earlier crossed the north Andhra Pradesh-south Odisha coast near Kalingapatnam.

Telangana and neighbouring states often see spillover rainfall from Bay of Bengal weather systems during the post-monsoon period in September and October.

The India Meteorological Department continues to track the system’s movement and update its warnings accordingly.
